Tool for Creating Tag Clouds

A blog post called "Critical Glanceability" by Ann-Marie Deitering (Oregon State University) includes an interesting looking tag cloud for "critical thinking," created by using wordle.net, a free site. You can enter a series of words or a url for a site with an RSS feed, like this LILi blog, in order to create a tag cloud image, with a number of choices for color and layout. Check out the LILi blog tag cloud.
